You can install vncviewer on Centos with the usual yum install vnc. If you want to create a automatic login for a remote server, you can do it easily. First, set the password by running vncpasswd. It will prompt you twice and store the passwd in a file called .vcn/passwd (it is encrypted). Then you can create a gnome application button by dragging the vncviewer icon to the gnome panel and editing. Just click properties and add your server as follows:

/usr/bin/vncviewer servername.com:port -passwd /user/.vnc/passwd

If you have completed the steps correctly, you should be able to click the vnc icon and connect to your server.
